摘要
阿尔及利亚首都阿尔及尔新机场项目的高架桥工程采用了法国专业公司TERRE ARMEE设计的预应力回填式匝道,其两侧为厚14 cm的预制混凝土墙,混凝土墙之间用优质回填土回填夯实,回填土中再埋设纤维带与混凝土墙连接,以防止其倾斜倒塌。详细介绍了预应力回填式匝道的施工技术。该技术施工简单、快捷,立面形象美观,具有较好的推广价值。
The overpass construction of the new airport project in the capital of Algeria, Algiers, used a prestressed backfill-type ramp designed by TERRE ARME, a French professional company. Two sides of the ramp are 14cm thick precast concrete walls. The concrete walls are backfilled with high quality backfill and properly tamped. A fiber band is embedded in the soil to connect with the concrete wall to prevent it from tilt and collapse. The construction technology of the prestressed backfill ramp is introduced in detail. The technology is simple and quick for construction, and has aesthetic facade image and greater promotional value.
